Abstract
Techniques are provided for enhancement of edges in image frames using depth information. A methodology implementing the techniques according to an embodiment includes receiving a color image frame and a depth map frame. The method also includes generating a sharpness mask to control the application of image sharpening to the color pixels. The sharpness mask is based on the value of depth pixels corresponding to the color pixels; and on properties of the depth camera that generated the color image frame, including depth of field, focal distance, and hyperfocal distance. The method further includes calculating sharpness strength for the color pixels. The sharpness strength is proportional to the value of the depth pixel corresponding to the color pixel. The method further includes applying a sharpening filter to the color image frame to enhance edge image features. The sharpening filter is based on the sharpness mask and the sharpness strength.
